Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments
- Exceptional holding power achieved through Class 3A thread fit for minimal backlash and secure fastening
- Maximum torque transmission with 3/16" hex drive design, preventing tool slippage during installation
- Enhanced grip and alignment from cup tip configuration, reducing component movement in assembled products
- Optimized durability with Rockwell B80 hardness, maintaining structural integrity under repeated use
- Reliable coarse threading using UNC 3/8"-16 pattern for quick installation and vibration resistance
- Space-saving headless design allowing flush mounting where clearance is limited
Professional Applications & Engineering Value
Engineered for precision industrial applications, this 3/8"-16 UNC set screw delivers critical performance in machinery assembly, automotive components, and permanent fixture installations. The 18-8 Stainless Steel composition provides inherent corrosion resistance, eliminating failure points in humid or chemical-exposed environments. With its Class 3A thread fit and cup tip design, the screw creates superior clamping force against shafts and collars, preventing rotational slippage in high-torque systems. The hex headless configuration enables installation in confined spaces while maintaining full engagement with standard 3/16" hex keys. These engineering features combine to solve common industrial challenges including vibration-induced loosening, material degradation, and installation accessibility limitations.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit tolerances per UNC standards with 3/8"-16 coarse threading and right-hand direction. Manufacturing complies with ASME B18.3 specifications for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety, ensuring suitability for global industrial applications.
